Q: What is the difference between the brightness and illuminance of LED street lights and the brightness and illumination of ordinary high-pressure sodium lamps?: There are differences, LED lights brightness and illumination will be greater, Zhongshan Ming inter lighting is specializing in the production of lightsAnd other outdoor lamps.

Q: What role does the light controller and driver play in the LED street light component?: At present, light emitting diode driver chip can be divided into constant voltage drive chip, constant current drive chip and pulse driver chip. Among them, constant voltage drive chip is generally our most common DC/DC boost chips. The advantage of this scheme is that chips are cheap and do not have complex peripheral circuits. But only constant voltage drive LED will drive the output current of the circuit is uncontrollable. LED brightness consistency cannot be guaranteed.

Q: How many watts is the LED street light 30W-900M?: The power is 30W, and the 900M is the current.

Q: Location of constant current source for LED street lamp: Solar street lighting controller is divided into two buck and step-up, Buck 50 yuan, step-up 80 yuan, the warranty for three years. Now the conventional 6 meter 30W power solar energy set price is about 1260 yuan, the detailed price ha needs to calculate according to the lighting time and the rainy days.

Q: What's in the lamppost of the LED street light? What is the function?: LED street lamp poles are: cross flow source, the role of the current stability, so that the light effect to achieve a stable effect, as well as variable pressure.

Q: How much is the LED terminal voltage of the solar street light controller v?: This voltage is often the voltage of the LED designer, not every vendor is the same, you can directly use the meter to measureHowever, I have contacted 2 companies of solar street light controller, output voltage is 12V, can be verified

Q: What ballast does the street lamp use?: You should first look at what is the light source, there are high pressure sodium lamp, low voltage lamp, high-pressure mercury lamp, metal halide lamp, ceramic metal halide lamp, LED lamp and energy-saving lamp, fluorescent lamp, electrodeless lamp and so on, to see what, some others do not need to ballast, general use now most of the high intensity discharge lamp, it is need to use high pressure sodium lamp, ballast or electronic ballast

Q: How long does the general power LED power supply cycle last? Such as street lights, power supplies, 150W, 180W?: The demands are different, the time is different. Of course, your technical decision time.
